The Mini-Ductor Specialty Coil Kit, No. IDIMD99-690, from Induction Innovations is designed for applications that demand more heat coverage and flexibility. Compatible with all Mini-Ductor Series tools, this kit includes oversized coils that excel at removing larger seized components in heavy duty, agriculture, construction, and more. Each coil lasts for several hundred uses or more, subject to use, and avoiding abrasion and overheating prevents premature wear to the coil. Coil insulation is coated to resist abrasion, but a new coil will be needed if the insulation is breached. The coils are flexible and can be bent or separated for a variety of applications.
